Stock wheels have some Bridgestone Potenza RE910's on them. Not a bad tire. TireRack calls them a performance all-season. And I'd have to agree. They held the road great in the dry, and damn good in the wet. Never gave me any problems on snow or ice either. I have these in 225/50/16.

My aftermarket wheels have Bridgestone Potenza RE750's on them. These are rated as Ultra-High performance summer tires. I'd agree once again. They stuck like white on rice to the road and cornering was never an issue. Very little flex in the sidewall. They gave for a stiff ride though. I'm going to disagree with TireRack on the wet weather traction. Personally, I thought they sucked in the rain. It felt pretty squirlley compared to my stock wheels. That could have something to do with the fact I have a smaller contact patch with the ground with these. I have these in 215/40/17. I'd probably buy these again but in 225/45/17, it's a shame my stock wheels have wider tires then my "racing rims".

Hmm...just did some checking. With the tires on my aftermarket rims, the overall diameter is 1.1 inches smaller then the stock wheels and tires. Even though the wheels themselves are an inch bigger. So, I guess my speedometer must be off something fierce. Well, not too much. Only 4.4% if my math is right.
But with the 225/45 I want to run, I'll be only a tenth of an inch off the stock overall diameter. Close enough. :thumbsup:
